<parameter name="confidence">0.9

## Technical details

An authenticated attacker can bypass URL destination validation in chatService.ts and labelScanService.ts by supplying a malicious custom AI service URL in the application settings. When the user triggers an affected AI workflow, the server makes an outbound POST request to the attacker-controlled destination with a bearer token, enabling internal network reconnaissance and information disclosure (AI system prompt leakage). The vulnerability is fixed in version 1.6.0 by implementing outbound URL policy restrictions for private and internal network addresses.
